Working on a project, I decided to test the responsiveness of my CSS. Suddenly, my page underwent a style transformation, especially my navbar (built with Bootstrap) changed completely. Upon inspecting, I noticed that properties were coming from a less/navbar.less file located in my supposed css folder (as indicated when hovered over), although I couldn't find such a file in the css folder. I didn't make any modifications leading to this, as I reverted to the original state, but the navbar remained altered. Please help, as this project is due soon.
Update: Upon further investigation, it appears that the bootstrap.min.css file is responsible for this change. It's puzzling how the same code looked normal earlier, but now the navbar has undergone significant changes without any modifications to the code.
